We designed the 509 R-Series Windproof Jersey with the hardcore racer in mind. Snocross, hillcross, grass drags, ice racing, hillclimbing, snowbiking, cross country, watercross…you get the drift. But truth be told, a lightweight, windproof, and breathable tech jersey is something any rider will appreciate. With ergonomic eight-panel design and a droptail back, it offers a pro-level fit with style that goes perfectly with your 509 kit.
